High-capacity bucket

On the left, with a light material, it fills the lorry in fewer cycles. On the right, filled with a dense material, it exceeds what the machine can lift. Computer-generated image.
Left: with a light material, it fills the lorry in fewer cycles. Right: filled with a dense material, it exceeds what the machine can lift. Computer-generated image.

More material per cycle, so fewer cycles.
The gain exists only if the product is light:
otherwise you fill it half way.

Other names for this tool: loading bucket, large-capacity bucket, light handling bucket, open-profile bucket.

What it is for

On the left, with a light material, it fills the lorry in fewer cycles. On the right, filled with a dense material, it exceeds what the machine can lift. Computer-generated image.

Left: with a light material, it fills the lorry in fewer cycles.
Right: filled with a dense material, it exceeds what the machine can lift.
What sets it apart:
it is made for volume, not for load — its body is wide, deep, and lightened as much as possible.
Computer-generated image.

It is made for products that take up space without weighing:
bulked topsoil, compost, mulch, light spoil, chippings.
The body is wide and deep, it is lightened as much as possible, and the edge is not made to attack ground in place.

The calculation is a calculation of cycles:
one bucket fewer is one slewing movement fewer and less fuel.
On picking up a heap that takes the whole day, the difference shows in the evening.

A high-capacity bucket filled with a dense product goes outside the load chart before it is full. It is the classic trap:
the tool is sized on one material and ends up loading another.
The volume is chosen on the real density of what you are picking up, not on the capacity shown.

02 Key technical data

On which machine?

They exist for machines from 6 to 31 t.
For example, on a 10 to 20 t excavator, the weight is generally from 930 to 3 600 kg.
A high-capacity bucket fits an excavator, via a mounting plate on all couplers, or a loader's coupler.
The excavator class: we calculate it with you for your machine.

What the tool does

For example, for a width of 3 000 mm: capacity from 3 000 to 8 000 l, weight from 1 800 to 3 000 kg.

What is needed on the hydraulic side

It is a passive tool: it needs no hydraulic connection.

03 Your study

Have your machine checked.

Tell us what you are picking up, where the heap is and how far away you have to set it down.
It is the reach that governs the volume, not the other way round.

What we need to answer you
  • Your machine Its make and its tonnage.
  • The auxiliary circuit Its flow in l/min, its pressure in bar, single- or double-acting.
  • The coupler in place Its system and its class.
  • The work The use, and the material.

Without these details, the study still begins: we will ask you for them.

High-capacity bucket tipping bulked topsoil into the body of a lorry
The volume is not only paid for at purchase: bucket full and arm extended, it is the machine's load chart that decides, not the bucket's data sheet.

04 Choice

What determines the choice

  • 01 — The product, and it first It is its density that fixes the acceptable volume.
  • 02 — The working reach A full bucket at the end of the arm is not a full bucket at the foot of the machine.
  • 03 — The discharge profile A light, damp product stays inside:
    it is the shape of the bottom that decides.
  • 04 — The empty weight What the bucket weighs empty comes off what it can carry full.
05 Check

What is checked before ordering

  • The material handled, named Soil, compost, mulch, aggregate:
    they are not the same buckets.
  • The maximum reach for picking up It governs the sizing, not the height of the heap.
  • The load chart at that reach Bucket full of the real material.
  • The interface Coupler designation or pin dimensions.
